  • Block copolymer
    Patent number: 6790908
    Abstract: The invention relates to a block copolymer and more especially to a thermoplastic elastomer block copolymer. The block copolymer is a diblock (block A)-(bloc B) copolymer, a triblock (block A)-(block B)-(block A), or a triblock (block A)-(block B)-(block C) copolymer, wherein block A is a stiff block, block B is a soft block, and block C is a stiff block. Block A or Block B comprises repetitive units deriving from segregation monomers.

  • Process for the manufacture of colloidal particles of controlled shape with water-soluble block copolymers comprising a hydrophobic block and a hydrophilic block
    Publication number: 20030027871
    Abstract: The invention relates to a process for the manufacture of colloidal particles of controlled shape, controlled size and controlled anisotropy with water-soluble block copolymer comprising at least one block of hydrophobic nature and at least one block of hydrophilic nature which can exhibit bulk organized structures and which can retain the morphology of the hydrophobic aggregates during dispersion in water. These aggregate dispersions can be used as thickening agents or as texturing agents for paints.
